Question

I’m using Hibernate 4.0.1.Final.

I’m having trouble binding a session when testing my service. I used ThreadLocalSessionContext.bind(session) to try and bind the session so that sessionFactory.getCurrentSession() returns a valid session but it isn’t working.

Calling sessionFactory.getCurrentSession() produces an exception (below). In my service class, I have:

public class OrganizationServiceImpl extends AbstractTransactionService implements OrganizationService {

public void saveOrganization(final String eodbId,
                             final String parentEodbId,
                             final String name,
                             final String description,
                             final String organizationType,
                             final String url,
                             final String stateAbbrev) {
    Session session = null;
    try {
        session = startOperation();
        final State state = orgDao.findStateByAbbrev(stateAbbrev);

…

protected Session startOperation() throws HibernateException {
    final Session session = sessionFactory.openSession();
    ThreadLocalSessionContext.bind(session);
    tx = session.beginTransaction();
    return session;
}

Here’s the JUnit test that invokes this service …

@Before
public void setupOrgServiceTest() { 
    Configuration config = new Configuration()
        .setProperty("hibernate.dialect", "org.hibernate.dialect.HSQLDialect")
        .setProperty("hibernate.connection.driver_class", "org.hsqldb.jdbcDriver")
        .setProperty("hibernate.connection.url", "jdbc:hsqldb:mem:lyceaTestDb")
        .setProperty("hibernate.connection.username", "sa")
        .setProperty("hibernate.connection.password", "")
        .setProperty("hibernate.connection.pool_size", "1")
        .setProperty("hibernate.connection.autocommit", "true")
        .setProperty("hibernate.cache.provider_class", "org.hibernate.cache.HashtableCacheProvider")
        .setProperty("hibernate.hbm2ddl.auto", "create-drop")
        .setProperty("hibernate.show_sql", "true")
        .addAnnotatedClass(Organization.class)
        .addAnnotatedClass(State.class); 
    final ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().applySettings(config.getProperties()).buildServiceRegistry();
    sessionFactory = config.buildSessionFactory(serviceRegistry);
    orgService = new OrganizationServiceImpl(sessionFactory);
}   // setupOrgSErviceTest

@Test
public void testSaveOrg() { 
    orgService.saveOrganization(testProps.getProperty("test.school.eodbId"),
                                testProps.getProperty("test.school.parent.eodbId"),
                                testProps.getProperty("test.school.name"), 
                                testProps.getProperty("test.school.description"), 
                                testProps.getProperty("test.school.org.type"), 
                                testProps.getProperty("test.school.url"), 
                                testProps.getProperty("test.school.state"));
}   // testSaveOrg

The exception I get when calling sessionFactory.getCurrentSession() is

You’ve not specified the Hibernate property which tells the SessionFactory to use the ThreadLocalSessionContext.

setProperty("hibernate.current_session_context_class", "thread")

This means that when your SessionFactory is built Hibernate doesn’t set the currentSessionContext. When you call getCurrentSession() there is nowhere for Hibernate to retrieve the current session from.

Other options are jta and managed.
